[0002] The names of circuit boards include circuit boards, PCB boards, aluminum substrates, high-frequency boards, thick copper boards, impedance boards, PCBs, ultra-thin circuit boards, ultra-thin circuit boards, printed (copper etching technology) circuit boards, etc. Circuit boards miniaturize and visualize circuits, and play an important role in the mass production of fixed circuits and the optimization of power layout.

[0003] At present, since there are multiple precision devices installed on the circuit board, protective measures need to be taken in advance to avoid damage during transportation. The existing technology usually adopts the method of inner and outer packaging. The inner packaging is filled with foam board to seal the gap between the circuit board and the carton to prevent the circuit board from hitting the carton, thereby playing an internal protection role. The outer packaging adopts a wooden box to cover the carton. The wooden box has high strength and plays an external protection role. However, due to the large number of circuit boards transported, the circuit boards in a single carton need to be stacked up and down for storage. During transportation, once a large vibration is encountered, it is easy to cause collisions between the circuit boards, thereby causing damage to the circuit boards. Utility Model Content

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-5 As shown, a circuit board includes a board body 1, and mounting holes 2 are opened on the four corners of the board body 1, and isolation components are arranged on the bottom surface of the board body 1 at positions corresponding to the mounting holes 2, and the isolation components include a fixing ring 3 and a connecting ring 4, and the fixing ring 3 and the connecting ring 4 are made of PVC material, which has high strength and toughness, corrosion resistance, and high durability, and an elastic member 5 is connected between the fixing ring 3 and the connecting ring 4, and the elastic member 5 is a spring with good elasticity, and connecting grooves 6 are opened on the top surface of the board body 1 at positions corresponding to the mounting holes 2, and a locking member is arranged on the connecting ring 4, and the locking member can be detachably connected to the inside of the connecting groove 6, so that before the circuit boards are transported, the circuit boards can be stacked together first, and during specific operations, the locking member on the upper circuit board can be locked. It is installed inside the connecting groove 6 of the lower circuit board to achieve the connection between the upper and lower circuit boards. The upper and lower circuit boards can be separated by the support of the elastic member 5 to avoid contact between the circuit boards. During transportation, once vibration occurs, causing the circuit boards to approach each other, the elastic member 5 will undergo elastic deformation to alleviate the impact, and can automatically reset after the force disappears, thereby avoiding collision between the circuit boards and preventing damage to the circuit boards. When installing the circuit board, the screw is passed through the mounting hole 2 and threadedly connected to the mounting point. Due to the extrusion of the screw, the elastic member 5 will undergo elastic deformation, thereby applying an upward thrust to the screw in the reverse direction, making the threaded connection more secure and not easy to loosen, thereby improving the installation firmness of the circuit board.

[0021] See also Figure 2-5As shown, the locking member includes a swivel 7, and the swivel 7 is rotatably connected to the connecting ring 4, an annular groove 8 is circumferentially opened on the inner side wall of the connecting groove 6, a clamping groove 9 connected with the annular groove 8 is vertically opened on the inner side wall of the connecting groove 6, and a clamping block 10 for clamping into the clamping groove 9 and the annular groove 8 in sequence is arranged on the swivel 7. When it is necessary to connect the upper and lower circuit boards together, the swivel 7 can be embedded in the connecting groove 6, so that the clamping block 10 is clamped into the groove 9 and slides to the connection point between the clamping groove 9 and the annular groove 8, and then the swivel 7 can be rotated so that the clamping block 10 is clamped into the annular groove 8. The annular groove 8 limits the clamping block 10, so that the locking member can be firmly installed in the connecting groove 6, thereby realizing the firm installation between the upper and lower circuit boards. When the circuit boards need to be separated, only the swivel needs to be rotated. 7, so that the card block 10 is rotated to the card slot 9, and it can be pulled out through the card slot 9 to release the lock, so that the circuit board can be separated. Through this arrangement, the disassembly and assembly between the circuit boards is relatively convenient and simple, saving time and effort. An elastic gasket 11 is arranged at the bottom of the swivel 7, and the elastic gasket 11 is made of rubber material. After the swivel 7 is connected to the inside of the connecting groove 6, the elastic gasket 11 will be compressed and deformed under pressure, thereby applying an upward thrust to the swivel 7 in the reverse direction, so that the card block 10 is in conflict with the top wall of the card slot 9, thereby improving the connection stability of the swivel 7 in the connecting groove 6. Among them, a plurality of anti-skid grooves 12 are circumferentially opened on the side wall of the swivel 7, thereby greatly increasing the friction coefficient on the side wall of the swivel 7, making it less likely to slip when the swivel 7 is rotated, and the operation is more labor-saving.
